HINGE.

Original application filed March'24, .1922, Serial-No.- 546,232. Divided and. this application filed May 21,

1924. Serial No. 714,848.

To all whom it may concern:

Be it known that I, STUART 7. Reasons, a citizen of the United States,and' a resident of New Britain, county of Hartford, State 5 ofConnecticut, have invented certain new and useful Improvements in aHinge, of which the following is a specification.

The aim of the present invention is to pro vide a hinge for use ontrunks-and the like,

andhaving various features of novelty and advantage, and, moreparticularly, to pro vide a hinge of this sort which is very 81111-1 piein construction and therefore may be economically manufactured, andwhich is very sturdy in that it is enabled to resist comparatively greatstrains and stresses placed upon it. j

This application is a divisional of my application Serial No. 5%,232,filed March 24, 1922.

I have shown for illustrative purposes two embodiments which the presentinvention.

of my improved the manner in V which the pintle is held against rotationrelative to one of the leaves; 1g. is a an; 111 Ml 1 1e F i bl l fro 1cl tl leaf a of the hinge'shown 'in Fig. 1 is formed;

Fig. 5 is a View similar to Fig. 1 but showing another embodiment of theinvention;

Fig. 6 is aperspective view of the parts of their planes. These knucklesare integral of the hinge of Fig. 5; and

Fig. 7 is a sectional view taken on line 77 of Fig. 5.

Referring to Figures 1 to 1-, inclusive, a and Z) denote the respectiveleaves of a trunk hinge, and 0 designates the pintle pivotallyconnecting the leaves together. Each of the leaves is preferablvconstructed of sheet metal by stamping out a blank to the desiredconfiguration and then drawing or pressing the blank to the requiredform. The leaf b has a knuckle 10 formed integral therewith by rollingthe metal upon itself. knuckle preferably rises above the plane of thebody portion of the leaf I). The leaf is provided with thelongitudinally extending In, the accompanying drawings, wherein Thiscorrugation'12, having one end merging into and formed integral with theknuckle 10. This corrugation 12' constitutes a reinforcing ribwhichprevents longitudinal flexure'of the body portion of the leaf and alsoserves to strengthen the knuckle 10, anchoring and bracing it, as itwere, against CllStOI'tlOll and bending, and particularly its juncturewith the body portion'of the leaf.

One end of the leaf (4 is upturned, thus providing a wall 15, which isupset or inclinedt'o the plane of the leaf a. This wall forms a socket,so to speak, for the reception of the knuckle 10 of-the leaf Z). At eachend of the wall or flange 15 and formed integral therewith is anapertured projection 16, these projections being bent down at rightangles to the leaf a so as to constitute the knuckles or bearingsbetween which the knuckle 10 is interposed. The pintlec is positionedand suitably secured in the aligned apertures or openings in theknuckles. The leaf a is pro vided with a longitudinally extending,reinforcing riblS, similar to the rib 12 of the leaf Z)- This rib 18, atits inner end, merges into and is integralwith theinclined wall 15. Theedge of the wall 15 may be recessed as at 20 and the edge of this recessconstitutes ashoulder or abutment which is adapt-' ed to engage, asshown by dotted lines of.

Fig. 2, against the rib 12 of the leaf Z2, and thus limit the extent towhich the leaves may be swung relative to one another. It will be seenthat since the projections or knuckles 16 are at right angles to theplane of the leaf a and to the length of the pintle c, the strains onthese knuckles are in the direction with the wall 15 of the leaf a, andthis wall is strengthened, anchored and braced by the rib 18. All ofwhich means that an extremeiii) against rotation in suitable mannerrelative to the knuckles 16 while the leaf 6 is adapted to swingrelative to the pintle. To this end the pintle opening 21 in one of theknuckles v16 is'noncircular, and that portion of the pintle positionedin this opening is of similar cross-section, thus preventing rotationbetween knuckles l6 and the pintle. lnthe present instance, the wail ofthe opening 21 in. the knuckle is notched as at 22, and the pintle is enianded into this notch, so that the pintle and knuckle are ininterlocked engage? inent.

Referring no :7 to the embodiment shown in Figs. to 7, inclusive theleaves a and 7/ are preferably formed of sheetinetal as in the precedingembodiment. The leaf Z) has two alined knuckles 10 10, formed. byrolling the metal back upon itself, and each rising above the plane ofthe leaf. Merging into each of the knuckles 10 and extendinglongitudinally of the leaf is a corrugation 12..

The leaf a has an end wall forming a socket for the knuckles 10, andthis end wall is reinforced by a pair of corrugations 18. r t each endof the wall or flange i5 is an apertured projection 16 corresponding inconstruction and arrangement to the knuckles or bearings 16 of thepreceding embodiment. The leaf a, in addition to the end knuckles 1%, isprovided with a pair of intermediate knuckles formed integral with aportion 31 extending from the end wall 15" and located centrallythereof. In forming the leaf a a blank is stamped out with the extendingportion 31 provided at each end with an ear. The blank is then pressedto shape with the ears bent down at right angles to the body portion ofthe extension Si so as to form the knuckles 30. It will be seen from thedrawings that the portion 31 is adapted to litin between the knuckles 10of the leaf Z). The pintle 21 is held against rotation in the aperturesof the knuckles 16 and 30 as for instance, by

notching one of the knuckles as at 2 and expanding the pintle lnto thenotch.

It is, of course, obvious that the invention -is susceptible of variousmodifications and changes which are within the .spirit of the lnventionwithout departing from the scope of the following clanns, it beingunderstood that the present disclosure of the invention having anrip-turned flange at one end integral therewith, projectionsconstituting knuckles integral with the side edges-of said flange anddisposed at rightangles thereto, and a longitudinally extendingcorrugation alined with said first corrugation and merging into andrising substantially to the top of said flange.

In a hinge of the character described comprising a pair of leavesconstructed of sheet metal, one of said leaves having a pair of knucklesformed by rolling one end of the leaf onto itself, and a pair oflongitudinally extending corrugations respectively merging into theknuckles; the otherof said leaves having an upturned flange at one endintegral therewith, projections constituting knuckles integral with theside edges of said flange and disposed at right angles thereto, aportion extending centrally from said flange and having end portionsbent down at r' ht angles to form knuckles in alineinent vith said noections and a corru ation merging into said flange; and a pintle eZ-;- tl U "l -'ll' "l'l f 1'' tent ing nou 1 salt xl'lllox es iOI'- ioiuingthe parts together.
